change in cam choice
change in cam choice Originally decided on AFR 205s and G5X3 but have to flycut pistons unless go with the 66cc head. Tony @ AFR suggested to go with a smaller cam and mill the head to 61-62cc for more compression. That would make a better combo. My question is what cam will yield the best combo, power being the most important issue? Ive seen the 224/228 in Tonys combo, looks good. Ive seen 226/230 XER in one of Norris motorsports cars that also looked good. I was wondering about the 233/239 ? Will it clear and how about the combo for power w/AFRs. Another ? what if I had the heads at 65cc with the G5X3 it would still have to put out more power than a stock headed G5X3 car which I saw produce over 400? Any input would really help seeing Im ready to purchase something so I can get started to making more power! THANKS AGAIN!!!!!!!!

your back to square one with the 233/239 as it will not clear the milled heads. if your going to flycut just stick with the x3. i vote fly cut and run the x3 or dont fly cut and run a smaller cam since compression is your friend. obviously even with the stock chambered afr's and an x3 you'll make a ton more power then an x3 cam only.
